Low-friction steering mechanism of field management machine

Abstract

The invention discloses a low-friction steering mechanism of a field management machine. The low-friction steering mechanism of the field management machine comprises a steering wheel seat and a steering wheel installed on the steering wheel seat, wherein a handrail assembly is fixedly installed on the steering wheel. The low-friction steering mechanism of the field management machine is characterized in that the top of the steering wheel seat is provided with a bearing groove, a locating shaft is fixedly arranged in the center of the bearing groove, a bearing is sheathed on the bottom end of the locating shaft, and the steering wheel is connected to the locating shaft through a shaft hole in the center in a sheathing manner; the steering wheel is clamped on the bearing through a clamping groove in the bottom surface, and the thickness of the bearing is larger than the sum of the depth of the bearing groove and the clamping groove. Since the bottom surface of the steering wheel is in contact with the bearing, during steering, no friction exists any more between the bottom surface of the steering wheel and the top surface of the steering wheel seat, the steering resistance is eliminated, the steering is enabled to be labor-saving and easy, serious wear does not occur between the bottom surface of the steering wheel and the top surface of the steering wheel seat, and the service life is long.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a low-friction steering mechanism of a field management machine. Background technique [0002] The pastoral management machine is specially designed for orchards, vegetable fields, greenhouses, hilly slopes and small fields. It is powered by a small diesel engine or gasoline engine and driven by an integral transmission gearbox or a belt clutch. It is light in weight and compact in size. Small size, simple structure, convenient operation, easy maintenance, stable and reliable work, long service life, low fuel consumption, high production efficiency, etc., are deeply loved by users. The steering mechanism of the pastoral management machine generally includes a turntable seat and a turntable mounted on the turntable seat, and the armrest assembly is fixedly installed on the turntable. In the low-friction steering mechanism of the traditional pastoral management machine, the c...

AI Technical Summary

Problems solved by technology

In the low-friction steering mechanism of the traditional pastoral management machine, the center of the top of the turntable seat is fixed with a positioning shaft, and the turntable is sleeved on the positioning shaft through the shaft hole in the center. In this way, the bottom surface of the turntable is in direct contact with the top surface of the turntable seat. , the bottom surface of the turntable and the top surface of the turntable seat have to rub against each other, which not only brings greater resistance to the steering, making the steering very laborious, but also wears a lot of both, and the service life is short
